FLY-FAN.

SPECIFICATION forming part of Letters Patent No. 234,713, dated November23, 1880.

Application filed March 20, 1880. (Model.)

To all whoml tt may concern:

Be it known that I, SAMUEL W. LAMBETH, a citizen of the United States,residing in the city land county of Philadelphia, and State ofPennsylvania, have invented a new and useful Im provement in Fly-Fans,which improvement is fully set forth in the following specification andaccompanying drawings, in which- Figure lis a side elevation, partly insection, of the portion of a ily-fan embodying my invention. Fig. 2 is ahorizontal section in line x x, Fig. l. Fig. 3 is a horizontal sectionof a modification.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention relates to an improvement in fans which have arms connectedto a staff, the rotation whereof is occasioned by a train of gearing',after the manner of clock-work, the motion of the blades which areattached to said arms serving to frighten llies and other insects.

The invention consists in so constructing the rotary staff that itsstrength is increased, and weight of the device reduced.

Referring to the drawings, A represents a staff or shaft rising from astand or base, B, containing a mechanical power-such as clockwork-forrotating said staff, as is well known in the class of fly-fans, avertically-adjustable collar, C, being fitted on said staff and heldthereon by suitable means.

The statil or shaft is necessarily long, and, as heretofore constructedof a solid rod, has been broken Or found to bend, thus causingdifficulty in adjusting the collar and variableness in the rotation ofthe fan-blades, and it adds considerable weight to the fan. Thesedefects are remedied by my invention, which consists in providing thefan with a hollow or tubular stati', whereby a stronger and lighter fanis produced, the staff preserves its straightness, and the blades rotateregularly, (which otherwise is hurtful to the eyes,) the fan thus beinga better and more serviceable article.

I do not claim, broadly, a rotary staff for a fly-fan, as I, am awarethat that is not new; neither do I claim the fan-'supporting collar Ormechanism fitted on said shaft, as that is well known; but

What I do claim as new, and desire t0 secure by Letters Patent, is-

The combination, with the stand B, containing the clock-work, and thecollar C, supporting the fan-blades, of the staff A, rising from thestand and connected to the clock-work, and made of tubular formthroughout its entire length, substantially as and for the purpose setforth.
